XC25BS5 Series ETR1502_002 PLL Clock Generator ICs with Built-In Divider/Multiplier Circuits (For Low Frequency Range) ■GENERAL DESCRIPTION The XC25BS5 series are high frequency, low power consumption PLL clock generator ICs with divider circuit & multiplier PLL circuit. Laser trimming gives the option of being able to select from divider ratios (M) of 1,3 to 2047 and multiplier ratios (N) of 6 to 2047. Output frequency (Q0) is equal to reference oscillation (fCLKin) multiplied by N/M, within a range of 3MHz to 30MHz. Q1 output is selectable from input reference frequency (f0), input reference frequency/2 (f0/2), ground (GND), and comparative frequency (f0/M). Further, comparative frequencies, within a range of 12KHz to 500KHz, can be obtained by dividing the reference oscillation. By halting operation via the CE pin, consumption current can be controlled and output will be one of high-impedance. ■FEATURES ■APPLICATIONS Output Frequency : 3MHz ~ 30MHz (Q0=fCLKin×N/M) Input Frequency (fCLKin) : 12kHz ~ 35MHz Divider Ratio (M) : Selectable from divisions of 1, 3~2047 Multiplier Ratio (N) : Selectable from multiplications of 6~2047 Output : 3-State Q1 output selectable from input reference ●Crystal oscillation modules ●Personal computers ●PDAs ●Portable audio systems ●Various system clocks oscillation, input reference oscillation/2, GND, comparative frequency.

(2) Rq0 and Rq1 are matching resistors. Their use is recommended in order to counter unwanted radiations. (3) Please place a by-pass capacitor and matching resistors as close to the IC as possible. It may be that the output cannot be locked if the by-pass capacitor is not close enough to the IC. Further, there is a possibility of unwanted radiation occurrence between the resistor and the IC pin if the matching resistor is not close enough to the IC. (4) When selecting GND for the Q1 pin, although the output of Q1 pin is GND level, it is also recommended that the Q1 pin be connected to GND pattern on the PCB. (5) When the CE pin is not controlled by external signals, it is recommended that a time constant circuit of R1=1kΩ ×C1 = 0.1μF be added for stability. (6) With this IC, output is achieved by dividing and multiplying the reference oscillation by means of the PLL circuit. In cases where this output is further used as a reference oscillation of another PLL circuit, it may be that the final output signal's jitter increases, so all necessary precautions should be taken to avoid this. (7) It is recommended that a low noise power supply, such as a series regulator, be used for the supply voltage. Using a power supply such as a switching regulator might lead to a larger jitter, which in turn may lead to an inability to lock due to the ripple of the switching regulator. (8) As for this IC, synchronization of input and output signal’s edge is not guaranteed though the input frequency operates to the output frequency multiply. 5/10 XC25BS5 Series ■REFERENCE LAND PATTERN ① Q1 Pin - reference oscillation, reference oscillation/2, comparative frequency ② Q1 Pin - GND 6/10 XC25BS5 Series ■AC CHARACTERISTIC WAVEFORMS 1) Output Rise Time / Output Fall Time DUTY Measurement Level 2) Duty Ratio DUTY Measurement Level 3) Output Start Time 7/10 XC25BS5 Series ■PACKAGING INFORMATION ●SOT-26 ●USP-6B ●USP-6B Recommended Pattern Layout ●USP-6B Recommended Metal Mask Design 8/10 XC25BS5 Series ■ MARKING RULE ●SOT-26 ① Represents product series MARK 5 PRODUCT SERIES XC25BS51xxMx ②③ Represents ② and ③ of ordering information MARK ② 0 SOT-26 (TOP VIEW) PRODUCT SERIES ③ 7 XC25BS5107Mx ④ Represents assembly lot number (Based on internal standards) ①,②,③ Represents product series ●USP-6B MARK ① ② ③ 2 ④ ⑤ ⑥ 1 3 USP-6B (TOP VIEW) 6 5 4 ③ PRODUCT SERIES ① ② B S 0 XC25BS50xxDx S 5 S XC25BS5SxxDx ④,⑤ Represents ② and ③ of ordering information (ex.)
